What is the conducting airways of the respiratory systems?

• Nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.
• Trachea, alveoli, capillaries
• Nasal passages, vocal cords, lungs
• Alveoli, diaphragm, pleura

What are the functions of the conducting airway?

• Regulating blood flow to the heart
• Producing oxygen for the body
• The functions of the conducting airway include filtering, warming, humidifying air, and providing a passage for air to the lungs.
• Absorbing nutrients from the air

What are the parts of the nasopharyngeal airways?

• Pharynx, esophagus, stomach
• Nose, mouth, oropharynx

• Larynx, trachea, bronchi
• Nasal passages, vocal cords, lungs

What are the parts of the laryngeal-tracheal airways?

• Larynx, trachea, epiglottis, vocal cords
• Trachea, bronchioles, pleura, diaphragm
• Pharynx, esophagus, stomach, lungs
• Bronchi, diaphragm, alveoli, nasal cavity

Answer explanation

The larynx connect the oropharaynx with the trachea

What are the respiratory bronchioles and their functions?

• Respiratory bronchioles are responsible for producing mucus in the lungs.
• Respiratory bronchioles are the smallest airways in the lungs that facilitate gas exchange and conduct air to the alveoli.
• Respiratory bronchioles are the main site of oxygen absorption in the bloodstream.
• Respiratory bronchioles are large airways that connect the trachea to the lungs.

What is the lung blood supply?

• The lung blood supply is provided by the coronary arteries.
• The lung blood supply includes the pulmonary arteries and pulmonary veins.
• The lung blood supply consists of the aorta and vena cava.
• The lung blood supply includes the hepatic arteries and veins.

What is ventilation/perfusion in the lungs?

• The process of oxygen diffusion into the bloodstream only.
• The amount of air in the lungs at rest.
• Ventilation/perfusion in the lungs is the relationship between the air reaching the alveoli (ventilation) and the blood flow in the surrounding capillaries (perfusion), essential for effective gas exchange.
• The total volume of blood in the body.

What is the average ventilation rate that the aveloi recieves

• 4 to 6 liters per minute
• 2 to 3 liters per minute
• 8 to 10 liters per minute
• 1 to 2 liters per minute

What is the average perfusion rate that the aveloi recieves

• 8 liters per minute per 100 grams of lung tissue
• 5 liters per minute per 100 grams of lung tissue
• 2 liters per minute per 100 grams of lung tissue
• 10 liters per minute per 100 grams of lung tissue

What is the "normal" VQ rate?

• 0.5
• 4.5 or 0.8

• 1.2
• 0.9
